Chances are good that young Mr. Bieber has never heard of Peter Noone, who performs here Sunday at Sycuan Casino. (Bieber, who turned 19 Friday, is too young to get into Sycuan, but that’s another story.)

Even so, it would be instructive for Bieber to study up on Noone, if not the latest edition of his band, Herman’s Hermits.

In his pre-Internet, pre-social-media heyday in the mid-1960s, Noone was an international teen-pop idol. He inspired deafening fan hysteria, not unlike Bieber now.

As the lead singer in Herman’s Hermits, Noone scored 18 U.S. Top 40 hits between late 1964 and early 1968. They include “I’m Into Something Good,” “No Milk Today” and the mildly psychedelic “Museum” (which was written by hippie troubadour Donovan and featured a studio band that included future Led Zeppelin co-founders Jimmy Page and John Paul Jones). With his perky voice and teen-idol looks, Noone inspired screams as often as Bieber does today.

Noone and his band also moved a lot of records, with worldwide sales of more than 40 million in less than 40 months. But the number Bieber should really focus on is 45.

That’s how many years it’s been since the Hermits’ last hit, although Noone scored a few minor subsequent solo successes. Most notable among these was 1971’s “Oh, You Pretty Things!” (written by David Bowie, who also played piano on Noone’s version).

Despite this decades-long commercial drought, Noone still loves his job, as evidenced by the 36 U.S. concert dates he has scheduled between now and October. Equally important, this consummate entertainer has a winning sense of humor, telling audiences: “I’m a 17-year-old boy trapped in a 65-year-old man’s body.” He also does a pitch-perfect Mick Jagger impersonation, which takes on greater resonance since the Hermits and the Rolling Stones sometimes used to play on the same concert bills.

Amusingly, Noone’s representatives last week refused to divulge the identities of his backing band, as if it would shock anyone to learn this younger, all-American lineup doesn’t include any original Hermits. (Sharp-eyed psychobilly fans may recognize ace drummer Dave Ferrara from his tenure with The Reach Around Rodeo Clowns in the 1990s.)

Will Bieber still be touring at 65? Will he willingly play an oldies circuit for fans who won’t be much younger than him? Should he?

Your guess is as good as mine. But if the Biebster is looking for a role model, Peter Noone may well be worth emulating.
